Vedclass · Answer

(C) Restriction endonucleases are a class of enzymes that recognize specific base sequences in $DNA$ and cut the $DNA$ duplex at specific locations. These enzymes are commonly referred to as 'molecular scissors' in biotechnology. They do not remove nucleotides from ends (that is the function of exonucleases) nor do they inhibit $DNA$ polymerase. Therefore,the correct function is to cut $DNA$ at specific sites.
